Description
本發明係關於一種液晶顯示器等光學顯示設備之生產系統及其生產方法。 The invention relates to a production system and a production method of an optical display device such as a liquid crystal display.
傳統上,於已知的液晶顯示器等光學顯示設備之生產系統中,係將貼合至液晶面板(光學顯示部件)的偏光板等光學組件,從長條薄膜切割出符合液晶面板之顯示區域尺寸的層片,包裝並輸送至另一生產線後,貼合至液晶面板(例如,參考日本專利特開第2003-255132號公報)。 Traditionally, in known production systems of optical display devices such as liquid crystal displays, optical components such as polarizing plates bonded to a liquid crystal panel (optical display component) are cut from a long film to fit the display area size of the liquid crystal panel. The laminated sheet is packaged and transported to another production line, and then bonded to a liquid crystal panel (for example, refer to Japanese Patent Laid-Open No. 2003-255132).
但是,上述習知結構中,考慮到液晶面板及層片的各尺寸偏差,以及對於液晶面板的層片之貼合偏差(位置偏差),會切割出較顯示區域略大的層片。因此,於顯示區域之周邊部分形成有多餘區域(邊框部),有阻礙機器之小型化的問題。 However, in the above-mentioned conventional structure, in consideration of the dimensional deviation of the liquid crystal panel and the laminations, and the lamination deviation (position deviation) of the laminations of the liquid crystal panel, a lamination slightly larger than the display area is cut. Therefore, there is a problem that an unnecessary area (frame portion) is formed in a peripheral portion of the display area, which hinders miniaturization of the device.
又,將光學組件貼合至液晶面板之前,雖然透過液晶面板之靜電消除等抑制灰塵附著於液晶面板,但貼合至液晶面板的光學組件之貼合面具有黏著性而容易附著灰塵,將容易產生貼合不良的問題。 In addition, before the optical component is bonded to the liquid crystal panel, although the dust is prevented from adhering to the liquid crystal panel through static elimination of the liquid crystal panel, the bonding surface of the optical component bonded to the liquid crystal panel has adhesiveness and is easy to attach dust, which will easily The problem of poor fit is caused.

At this time, after the second single-sided bonding panel P12 and the opposing portion of the display area P4 (each optical component (the first optical component F11 and the second optical component F12)) are left, each optical component in a frame shape remains. The remaining portions of the layers (the first optical component F1 and the second optical component F2) can be separated from each other. The remaining part of the second optical component layer F2 will be in the form of a plurality of connected ladders (refer to FIG. 2), and the remaining part is rolled up with the remaining part of the first optical component layer F1 to the second recycling part 15 d.

參考第1圖,第三校準裝置17將液晶面板P顯示面側朝向上側面的第二單面貼合面板P12進行正/反面反轉,使得液晶面板P之背光側朝向上側面,並進行與該第一校準裝置11及第二校準裝置14相同的校準。即,第三校準裝置17係根據儲存於控制裝置20之光軸方向檢查資料及該攝影機C的攝影資料,決定相對於第三貼合裝置18的第二單面貼合面板P12之部件寬度方向及迴轉方向上的位置。在該狀態中,第二單面貼合面板P12被引導至第三貼合裝置18之貼合位置。 Referring to FIG. 1, the third calibration device 17 reverses the front / reverse side of the second single-sided bonding panel P12 with the display surface side of the liquid crystal panel P facing the upper side, so that the backlight side of the liquid crystal panel P faces the upper side, and performs The first calibration device 11 and the second calibration device 14 perform the same calibration. That is, the third calibration device 17 determines the width direction of the component with respect to the second single-sided bonding panel P12 of the third bonding device 18 based on the inspection data of the optical axis direction stored in the control device 20 and the photographic data of the camera C. And position in the direction of rotation. In this state, the second single-sided bonding panel P12 is guided to the bonding position of the third bonding device 18.

輸送裝置19係將分離層片SS作為載件而連續地輸送複數個第三光學組件F13。第三光學組件層F3及分離層片SS為具有於該部件寬度方向上對應於液晶面板P之顯示區域P4的寬度(相當於本實施形態中顯示區域P4之整體寬度以上,液晶面板P之整體寬度以下的寬度)的長條狀。分離層片SS係重疊並可分離的貼合於第三光學組件層F3(第三光學組件F13)。以下,將分離層片SS與第三光學組件層F3之組合稱作第三光學組件層體F3S。 The transport device 19 continuously transports the plurality of third optical units F13 using the separation layer sheet SS as a carrier. The third optical component layer F3 and the separation layer sheet SS have a width corresponding to the display area P4 of the liquid crystal panel P in the width direction of the component (equivalent to the entire width of the display area P4 or more in this embodiment, and the entire liquid crystal panel P Strip width). The separation layer sheet SS is overlapped and separably bonded to the third optical element layer F3 (third optical element F13). Hereinafter, the combination of the separation layer sheet SS and the third optical element layer F3 is referred to as a third optical element layer body F3S.
輸送裝置19係具備:滾筒保持部19a(捲出部),係夾持第三料捲滾筒R3並從該第三料捲滾筒R3沿第三光學組件層體F3S之長邊方向將第三光學組件層體F3S捲出;單數或複數個(圖中僅顯示一個)導引滾筒19b,沿特定之層片輸送路線將從第三料捲滾筒R3捲出之第三光學組件層體F3S引導至第三貼合裝置18的貼合位置為止,沿第三光學組件層體F3S之分離層片SS側捲繞;切斷裝置19c(切斷部),會對層片輸送路線上之第三光學組件層體F3S進行殘留下分離層片SS的半切斷;刀刃19d,將半切斷後之第三光學組件層體F3S的分離層片SS側於銳角進行捲繞,使第三光學組件F13從分離層片SS分離,並將第三光學組件F13供給至貼合位置;以及分離層片回收部19e,捲取通過刀刃19d後獨立存在之分離層片SS。 The conveying device 19 is provided with a roller holding portion 19a (rolling-out portion) for clamping the third roll roller R3 and from the third roll roller R3 along the long side direction of the third optical module layer body F3S. The component layer body F3S is rolled out; the singular or plural (only one shown in the figure) guide roller 19b is guided to the third optical component layer body F3S rolled out from the third material roll roller R3 along a specific layer conveying route to Up to the bonding position of the third bonding device 18, it is wound along the separation layer sheet SS side of the third optical component layer body F3S; the cutting device 19c (cutting section), The component layer body F3S performs a half cut of the remaining separation layer sheet SS; the blade 19d winds the separation layer sheet SS side of the third optical module layer body F3S after the half cut at an acute angle, so that the third optical module F13 is removed from the separation layer The sheet SS is separated, and the third optical component F13 is supplied to the bonding position; and the separation layer sheet recovery part 19e winds up the separation layer sheet SS which exists independently after passing through the blade 19d.
位於輸送裝置19之起點的滾筒保持部19a與位於輸送裝置19 之終點的分離層片回收部19e係例如為相互同步驅動。藉此,滾筒保持部19a係朝第三光學組件層體F3S之輸送方向捲出第三光學組件層體F3S,且分離層片回收部19e則捲取通過刀刃19d後獨自存在之分離層片SS。 The roller holding portion 19a located at the starting point of the conveying device 19 and the conveying device 19 The separation layer recovery unit 19e at the end point is driven in synchronization with each other, for example. Thereby, the roller holding portion 19a rolls out the third optical component layer body F3S in the conveying direction of the third optical component layer body F3S, and the separation layer sheet recovery portion 19e winds up the separation layer SS that exists alone after passing through the blade 19d .
切斷裝置19c係當第三光學組件層體F3S捲出特定長度時,在垂直第三光學組件層體F3S之長邊方向(捲出方向)的寬度方向上,殘餘分離層片SS地沿整體寬度對第三光學組件層體F3S進行切斷(即僅切斷第三光學組件層F3)。切斷裝置19c係透過第三光學組件層體F3S輸送中的張力,在不使得分離層片SS斷裂的情況下調整切斷刀片的前後位置。 The cutting device 19c is such that when the third optical component layer body F3S is rolled out a specific length, the residual separation layer SS is along the whole in a width direction perpendicular to the long side direction (rolling direction) of the third optical component layer body F3S. The width cuts the third optical component layer body F3S (that is, only the third optical component layer F3 is cut). The cutting device 19c adjusts the forward and backward positions of the cutting blade without breaking the separation layer sheet SS through the tension in the conveyance of the third optical component layer F3S.
於該切斷後之第三光學組件層體F3S處,在第三光學組件層體F3S之寬度方向的整體寬度上形成有切割線。 A cut line is formed on the entire width in the width direction of the third optical component layer body F3S at the third optical component layer body F3S after the cutting.
此處,於刀刃19d之前端部附近,在第三貼合裝置18之貼合位置附近的面板輸送上游側之部位處,設置有檢測該部位中第三光學組件F13的捲出方向下游側之切斷端的第一檢測攝影機22。第一檢測攝影機22之檢測資料係傳送至控制裝置20。控制裝置20於例如第一檢測攝影機22檢測出第三光學組件F13之下游側端的時點時,係暫時停止輸送裝置19。其後,於第一檢測攝影機22檢測出第二單面貼合面板P12之下游側端的時點時,控制裝置20係驅動輸送裝置19,使第二單面貼合面板P12與第三光學組件F13可同步地引導至第三貼合裝置18的貼合位置。 Here, near the front end of the blade 19d, at a portion on the upstream side of the panel conveyance near the bonding position of the third bonding device 18, a detection is performed on the downstream side of the third optical component F13 in this portion. The first detection camera 22 at the cut end. The detection data of the first detection camera 22 is transmitted to the control device 20. The control device 20 temporarily stops the conveying device 19 when, for example, the first detection camera 22 detects a downstream end of the third optical unit F13. Thereafter, when the first detection camera 22 detects the downstream end of the second single-sided bonding panel P12, the control device 20 drives the conveying device 19 so that the second single-sided bonding panel P12 and the third optical component F13 It can be synchronously guided to the bonding position of the third bonding device 18.
另一方面,於第一檢測攝影機22之捲出方向上游側,在切斷裝置19c之捲出方向下游側相距一個第三光學組件F13之距離的部位處,設置有同樣檢測第三光學組件F13的捲出方向下游側之切斷端的第二檢測攝影機23(檢測部)。第二檢測攝影機23的檢測資料亦傳送至控制裝置20。控制裝置20係以 例如切斷裝置19c進行第三光學組件層F3切斷步驟後將其捲出,在第二檢測攝影機23檢測出其切斷端(第三光學組件層F3之最上游側的切割線)的時點時,暫時停止輸送裝置19。此時,以切斷裝置19c進行第三光學組件層F3的切斷步驟。即,沿第二檢測攝影機23之檢測位置(相當於第三光學組件層F3中第二檢測攝影機23之光軸延長線上)與切斷裝置19c之切斷位置(相當於第三光學組件層F3中切斷裝置19c的切斷刀片前後位置)間的層片輸送路線之距離係相當於第三光學組件F13的長度。 On the other hand, on the upstream side in the unwinding direction of the first detection camera 22, a third optical unit F13 is also provided at a position on the downstream side in the unwinding direction of the cutting device 19c from a third optical unit F13. The second detection camera 23 (detection unit) at the cut-off end on the downstream side in the unwinding direction. The detection data of the second detection camera 23 is also transmitted to the control device 20. The control device 20 is For example, the cutting device 19c rolls out the third optical component layer F3 after the cutting step, and when the second detection camera 23 detects the cutting end (the cutting line on the most upstream side of the third optical component layer F3) At that time, the conveying device 19 is temporarily stopped. At this time, the cutting step of the third optical element layer F3 is performed by the cutting device 19c. That is, along the detection position of the second detection camera 23 (corresponding to the extension line of the optical axis of the second detection camera 23 in the third optical component layer F3) and the cutting position of the cutting device 19c (corresponding to the third optical component layer F3) The distance between the layer conveying paths between the cutting blades in the middle cutting device 19c and the front and rear positions) corresponds to the length of the third optical module F13.
在切割出貼合於例如同一尺寸液晶面板P之第三光學組件F13的情況中,係於第三光學組件層體F3S的長邊方向上等間隔地形成有該切割線。第三光學組件層F3係藉由複數個切割線在長邊方向劃分出複數個分區,於該第三光學組件層F3中長邊方向上由相鄰的一對切割線所夾區域係各自作為第三光學組件F13。第三光學組件F13的長度係為本實施形態中顯示區域P4的整體長度以上,且為液晶面板P的整體長度以下。 When the third optical element F13 bonded to the liquid crystal panel P of the same size is cut out, for example, the cutting lines are formed at regular intervals in the long side direction of the third optical element layer body F3S. The third optical component layer F3 is divided into a plurality of partitions in the long-side direction by a plurality of cutting lines. In the third optical component layer F3, the areas sandwiched by the adjacent pair of cutting lines in the long-side direction are each regarded as Third optical component F13. The length of the third optical element F13 is equal to or greater than the entire length of the display area P4 in this embodiment, and is equal to or smaller than the entire length of the liquid crystal panel P.
又,切斷裝置19c可沿第三光學組件層體F3S之層片輸送路線移動。透過該移動步驟,將改變第二檢測攝影機23之檢測位置與切斷裝置19c之切斷位置間的層片輸送路線之距離。切斷裝置19c的移動係透過控制裝置20所控制,在以例如切斷裝置19c進行第三光學組件層F3的切斷之後,捲出一個第三光學組件F13之距離時,當切斷端位置與指定位置有偏差的情況中,該偏差係藉由切斷裝置19c的移動以進行修正。 In addition, the cutting device 19c can move along the sheet conveyance path of the third optical element layer body F3S. Through this moving step, the distance of the laminar conveyance path between the detection position of the second detection camera 23 and the cutting position of the cutting device 19c will be changed. The movement of the cutting device 19c is controlled by the control device 20. After the third optical component layer F3 is cut by the cutting device 19c, for example, the third optical component F13 is rolled out. When there is a deviation from the designated position, the deviation is corrected by the movement of the cutting device 19c.
不過,亦可藉由切斷裝置19c的移動來對應長度相異之第三光學組件F13的切斷。又,亦可使得切斷裝置19c及第二檢測攝影機23至少一者在層片輸送方向的一方向上移動,藉以進行該修正或第三光學組件F13的長度 改變。又,雖然切斷裝置19c與第二檢測攝影機23相互接近,但為了防止切斷裝置19c移動等所伴隨的第二檢測攝影機23振動,較佳地可由其它框架所支撐。 However, the cutting of the third optical module F13 having a different length may also be performed by the movement of the cutting device 19c. In addition, at least one of the cutting device 19c and the second detection camera 23 may be moved upward in one of the slice conveying directions to perform the correction or the length of the third optical module F13. change. In addition, although the cutting device 19c and the second detection camera 23 are close to each other, in order to prevent the second detection camera 23 accompanying the movement of the cutting device 19c and the like from being vibrated, it is preferably supported by another frame.
刀刃19d係配置於滾筒輸送機5下方,於第三光學組件層體F3S的寬度方向上至少延伸至其整個寬度地被形成。刀刃19d係於半切斷後之第三光學組件層體F3S的分離層片SS側呈滑動接觸地,使分離層片SS捲繞過此銳角。 The blade 19d is disposed below the roller conveyor 5 and is formed to extend at least the entire width of the third optical component layer body F3S in the width direction. The blade 19d is on the side of the separation layer sheet SS of the third optical component layer body F3S after half-cutting, and the separation layer sheet SS is wound through this acute angle.
第三光學組件層體F3S在刀刃19d呈銳角處折返時,第三光學組件F13會從分離層片SS分離。刀刃19d係配置於接近夾壓滾筒21的面板輸送上游側。藉由刀刃19d從分離層片SS分離的第三光學組件F13係重疊至滾筒輸送機5所輸送之液晶面板P的下側面,且被引導至夾壓滾筒21的一對貼合滾筒之間。 When the third optical component layer body F3S is folded back at an acute angle of the blade 19d, the third optical component F13 is separated from the separation layer sheet SS. The blade 19 d is disposed on the upstream side of the panel conveyance near the nip roller 21. The third optical component F13 separated from the separation layer SS by the blade 19d is superimposed on the lower side of the liquid crystal panel P conveyed by the roller conveyor 5 and is guided between a pair of laminating rollers sandwiching the roller 21.
夾壓滾筒21具有於軸線方向相互平行配置的一對貼合滾筒。 The nip roller 21 includes a pair of bonding rollers arranged in parallel with each other in the axial direction.
一對貼合滾筒之間形成有指定間隙,該間隙內即為第三貼合裝置18的貼合位置。將第二單面貼合面板P12及第三光學組件F13重合導入該間隙內。該等第二單面貼合面板P12及第三光學組件F13係於該貼合滾筒之間受夾壓,並送往面板輸送下游側。藉此,便可形成將第三光學組件F13貼合至第二單面貼合面板P12的雙面貼合面板P13(參考第7圖)。 A specified gap is formed between the pair of bonding drums, and the gap is the bonding position of the third bonding device 18. The second single-sided bonding panel P12 and the third optical component F13 are overlapped and introduced into the gap. The second single-sided bonding panel P12 and the third optical component F13 are sandwiched between the bonding rollers and sent to the downstream side of the panel transportation. Thereby, a double-sided bonding panel P13 (refer to FIG. 7) in which the third optical component F13 is bonded to the second single-sided bonding panel P12 can be formed.
雙面貼合面板P13通過圖中未顯示之缺陷檢查裝置,以檢查是否有缺陷(貼合不良等)後,輸送至下游步驟進行其它處理。 The double-sided bonding panel P13 passes a defect inspection device not shown in the figure to check whether there is a defect (bad bonding, etc.), and then conveys it to a downstream step for other processing.
此處,一般長條狀光學薄膜(相當於各光學組件層(第一光學組件層F1、第二光學組件層F2及第三光學組件層F3))係將經二色性染料進行染色之樹脂薄膜朝一軸延伸地製造,光學薄膜之光軸方向與樹脂薄膜之延伸方向概 略一致。但是,關於光學薄膜之光軸,光學薄膜全體並非相同,於光學薄膜之寬度方向上略有差異。 Here, a generally long optical film (corresponding to each optical component layer (first optical component layer F1, second optical component layer F2, and third optical component layer F3)) is a resin that is dyed with a dichroic dye. The film is manufactured to extend in one axis. The optical axis direction of the optical film and the extending direction of the resin film are roughly Slightly consistent. However, regarding the optical axis of the optical film, the entire optical film is not the same, and there are slight differences in the width direction of the optical film.
因此,欲沿其寬度方向將複數個光學顯示部件貼合至光學薄膜的情況中,較佳地係依據光學薄膜之光軸方向進行光學顯示部件的校準。 Therefore, in the case where a plurality of optical display components are to be bonded to the optical film along the width direction, it is preferable to perform the calibration of the optical display component according to the optical axis direction of the optical film.
這對於抑制光學顯示設備單元之光軸偏差,改善色彩度及對比度是有效的。 This is effective for suppressing the deviation of the optical axis of the optical display device unit and improving the chroma and contrast.
作為偏光薄膜之光學薄膜,為了遮斷沿一方向上振動之光線以外的光線,係以例如碘或二色性染料等進行染色。不過,光學薄膜處亦可進一步層積有剝離薄膜或保護薄膜。 An optical film as a polarizing film is dyed with, for example, iodine or a dichroic dye in order to block light other than the light that vibrates in one direction. However, a release film or a protective film may be further laminated on the optical film.
檢查光學薄膜之光軸方向的檢查裝置,係具備:光源,係配置於光學薄膜之正/反面的一側之面的接近位置;以及分析儀,係配置於光學薄膜之正/反面的另一側之面的接近位置,配置於光源的反對側。分析儀會接收自光源照射並透射光學薄膜的光線,檢測該光線強度,藉以檢測出光學薄膜之光軸。分析儀例如可於光學薄膜之寬度方向上移動,可於光學薄膜之寬度方向上的任意位置(依使用條件所選擇的位置)檢測光軸。 An inspection device for inspecting the optical axis direction of an optical film includes: a light source, which is disposed at a close position on one side of the optical film's front / reverse surface; and an analyzer, which is disposed on the other side of the optical film's front / reverse surface. The close position of the side surface is arranged on the opposite side of the light source. The analyzer receives the light from the light source and transmits the optical film, and detects the intensity of the light to detect the optical axis of the optical film. The analyzer can be moved, for example, in the width direction of the optical film, and can detect the optical axis at an arbitrary position in the width direction of the optical film (position selected according to the use conditions).
本實施形態的情況中,該檢查裝置所獲得之各光學組件層(第一光學組件層F1、第二光學組件層F2及第三光學組件層F3)之光軸方向的檢查資料係與各光學組件層(第一光學組件層F1、第二光學組件層F2及第三光學組件層F3)之長邊方向位置與寬度方向位置資料連結地儲存於控制裝置20之記憶體。經檢查之後,各自捲取各光學組件層(第一光學組件層F1、第二光學組件層F2及第三光學組件層F3),以形成各料捲滾筒(第一料捲滾筒R1、第二料捲滾筒R2及第三料捲滾筒R3)。以下,各光學組件層(第一光學組件層F1、第二光學組件 層F2及第三光學組件層F3)可統稱為光學組件層FX,貼合至各光學組件層(第一光學組件層F1、第二光學組件層F2及第三光學組件層F3)的液晶面板P及各單面貼合面板(第一單面貼合面板P11及第二單面貼合面板P12)可統稱為光學顯示部件PX。 In the case of this embodiment, the inspection data in the optical axis direction of each optical component layer (the first optical component layer F1, the second optical component layer F2, and the third optical component layer F3) obtained by the inspection device is related to each optical The position data of the component layers (the first optical component layer F1, the second optical component layer F2, and the third optical component layer F3) are stored in the memory of the control device 20 in a manner that the position data in the longitudinal direction and the position in the width direction are linked. After inspection, each optical component layer (first optical component layer F1, second optical component layer F2, and third optical component layer F3) is rolled up to form each roll roll (first roll roll R1, second Roll roll R2 and third roll roll R3). Hereinafter, each optical component layer (first optical component layer F1, second optical component Layer F2 and the third optical component layer F3) may be collectively referred to as an optical component layer FX, and a liquid crystal panel bonded to each optical component layer (the first optical component layer F1, the second optical component layer F2, and the third optical component layer F3) P and each of the single-sided laminated panels (the first single-sided laminated panel P11 and the second single-sided laminated panel P12) may be collectively referred to as an optical display component PX.
此處,構成光學組件層FX之偏光薄膜係例如經二色性染料進行染色之PVA薄膜,並朝一軸延伸所形成,由於延伸時會有PVA薄膜厚度之不均勻或二色性染料染色不均勻等,易造成光學組件層FX之寬度方向內側與寬度方向外側之光軸方向相異的問題。 Here, the polarizing film constituting the optical component layer FX is, for example, a PVA film dyed with a dichroic dye and extended toward one axis. Due to the unevenness of the thickness of the PVA film or the uneven dyeing of the dichroic dye when stretched. For example, the optical axis direction of the widthwise inner side and the widthwise outer side of the optical element layer FX is likely to cause a problem.
此處,本實施形態中,根據預先儲存於控制裝置20之光學組件層FX各部位中的光軸面內分佈檢查資料,進行與其貼合之光學顯示部件PX的校準後,將光學顯示部件PX貼合至光學組件層FX。 Here, in this embodiment, the optical display component PX is calibrated based on the distribution inspection data in the optical axis plane of each part of the optical component layer FX of the control device 20 in advance, and the optical display component PX is aligned therewith. Bonded to the optical component layer FX.
具體而言,於光學組件層FX中貼合光學顯示部件PX的部位面內,例如找出相對於指定之基準軸(長邊方向軸等)角度最大的光軸與最小的光軸,將各該光軸所產生的角度均分後的軸作為該部位之平均光軸,以該軸為基準進行光學顯示部件PX的校準。 Specifically, in the area where the optical display component PX is bonded to the optical component layer FX, for example, the optical axis with the largest angle and the smallest optical axis with respect to a designated reference axis (longitudinal axis, etc.) are found, and each The axis obtained by dividing the angle generated by the optical axis is the average optical axis of the part, and the optical display component PX is calibrated based on the axis.
藉此,即使是在光學組件層FX之寬度方向上相異位置處貼合光學顯示部件PX的情況,可抑制相對光學顯示部件PX之基準位置的光學組件層FX之光軸方向偏差,光軸公差可幾乎為0°(容許公差為±0.25°)。 Thereby, even when the optical display component PX is bonded at different positions in the width direction of the optical component layer FX, the optical axis direction deviation and optical axis of the optical component layer FX relative to the reference position of the optical display component PX can be suppressed. The tolerance can be almost 0 ° (allowable tolerance is ± 0.25 °).
不過,亦可於捲出光學組件層FX的同時檢測出光軸方向,並根據該檢測資料進行光學顯示部件PX的校準。又,前述各種校準方式不限於光學組件層FX之光軸方向為0°及90°的情況,亦可適用於任意角度(依光學顯示部件之目的所對應的角度)的情況。 However, the optical axis direction may be detected while the optical component layer FX is rolled out, and the optical display component PX may be calibrated based on the detection data. In addition, the aforementioned various calibration methods are not limited to the case where the optical axis directions of the optical component layer FX are 0 ° and 90 °, and can also be applied to an arbitrary angle (an angle corresponding to the purpose of the optical display component).
又,第3圖係於相對較寬的光學組件層FX之寬度方向上並列貼合有三個光學顯示部件PX的範例。本發明並不限於第3圖所示之範例,亦可於光學組件層FX之寬度方向上並列貼合有二個以下或四個以上的光學顯示部件PX,亦可將相對較窄的光學組件層FX沿寬度方向排列複數個,並各自貼合光學顯示部件PX。 FIG. 3 is an example in which three optical display components PX are bonded in parallel in the width direction of a relatively wide optical component layer FX. The present invention is not limited to the example shown in FIG. 3, and two or less or four or more optical display components PX may be laminated side by side in the width direction of the optical component layer FX, and a relatively narrow optical component may also be bonded. A plurality of layers FX are arranged in the width direction, and each of the layers FX is bonded to the optical display component PX.
參考第4圖,液晶面板P,係具備:第一基板P1,係例如TFT基板所構成的長方形基板;第二基板P2,係對向第一基板P1而被配置的相同形狀之長方形基板;以及液晶層P3,係封入第一基板P1與第二基板P2之間。不過,為了圖示方便起見,省略剖面圖中的各層剖面線。 Referring to FIG. 4, the liquid crystal panel P includes: a first substrate P1, which is, for example, a rectangular substrate composed of a TFT substrate; a second substrate P2, which is a rectangular substrate of the same shape, which is arranged opposite to the first substrate P1; and The liquid crystal layer P3 is sealed between the first substrate P1 and the second substrate P2. However, for convenience of illustration, the hatching of each layer in the cross-sectional view is omitted.
參考第6圖,第一基板P1係使第一基板P1外周緣之三個側邊沿第二基板P2相對應之三個側邊配置,且其外周緣剩餘之一側邊則延伸至第二基板P2相對應之一側邊的外側。藉此,於第一基板P1之一側邊處設置延伸至第二基板P2外側的電子部件安裝部P5。 Referring to FIG. 6, the first substrate P1 is configured such that three sides of the outer periphery of the first substrate P1 are arranged along three sides corresponding to the second substrate P2, and one of the remaining sides of the outer periphery extends to the second substrate The substrate P2 corresponds to the outside of one of the sides. Thereby, an electronic component mounting portion P5 extending to the outside of the second substrate P2 is provided at one side of the first substrate P1.
參考第5圖,第二切斷裝置16以攝影機16a等檢測工具檢測顯示區域P4之外周緣,並沿顯示區域P4之外周緣等切斷第一光學組件層F1及第二光學組件層F2。顯示區域P4之外側處係設置有將第一基板P1及第二基板P2接合之密封劑等設置用特定寬度的邊框部G,於該邊框部G之寬度內以第二切斷裝置16進行雷射切斷。 Referring to FIG. 5, the second cutting device 16 detects the outer periphery of the display area P4 with a detection tool such as a camera 16 a, and cuts the first optical component layer F1 and the second optical component layer F2 along the outer periphery of the display area P4 and the like. Outside the display area P4, a frame portion G having a specific width for installation, such as a sealant that joins the first substrate P1 and the second substrate P2, is provided. Within the width of the frame portion G, a second cutting device 16 is used for lightning. Shoot off.
如第9圖所示,單獨對樹脂製的光學組件層FX進行雷射切斷時,光學組件層FX之切斷端t可能因熱變形而膨脹或呈波浪形。因此,將雷射切斷後之光學組件層FX貼合至光學顯示部件PX的情況,光學組件層FX處易產生空氣混入或變形等貼合不良問題。 As shown in FIG. 9, when the resin-made optical element layer FX is subjected to laser cutting alone, the cutting end t of the optical element layer FX may expand or be wavy due to thermal deformation. Therefore, in the case where the laser-cut optical component layer FX is bonded to the optical display component PX, the optical component layer FX is liable to cause poor bonding problems such as air intrusion or deformation.
另一方面,如第8圖所示,於液晶面板P貼合好光學組件層FX之後,以雷射切斷光學組件層FX的本實施形態中,光學組件層FX之切斷端t會受到液晶面板P之玻璃表面支撐。因此,光學組件層FX之切斷端t不會產生膨脹或波浪形,且於液晶面板P之貼合後進行故不會有前述貼合不良問題。 On the other hand, as shown in FIG. 8, after the optical element layer FX is bonded to the liquid crystal panel P, in the present embodiment in which the optical element layer FX is cut by laser, the cutting end t of the optical element layer FX is subjected to The glass surface of the liquid crystal panel P is supported. Therefore, the cut-off end t of the optical component layer FX does not cause expansion or wave shape, and is performed after the liquid crystal panel P is bonded, so there is no problem of the aforementioned poor bonding.
於液晶面板P上切斷光學組件層FX的情況中,雷射加工機之切割線的振動幅度(公差)係較切斷刀片之切割線的振動幅度更小。因此本實施形態中,與使用切斷刀片切斷光學組件層FX的情況相比,可使得該邊框部G的寬度更窄,可達到液晶面板P的小型化及(或)顯示區域P4的大型化。這種光學組件層可應用於近年來之智慧型手機或平板電腦終端等,需要在機殼尺寸之限制下將顯示畫面放大的高機能行動裝置。 In the case where the optical component layer FX is cut on the liquid crystal panel P, the vibration amplitude (tolerance) of the cutting line of the laser processing machine is smaller than that of the cutting line of the cutting blade. Therefore, in this embodiment, compared with the case where the optical element layer FX is cut using a cutting blade, the width of the frame portion G can be made narrower, and the size of the liquid crystal panel P can be reduced, and (or) the display area P4 can be large. Into. Such an optical component layer can be applied to a smart phone or a tablet terminal in recent years, and the high-performance mobile device that needs to enlarge the display screen under the limitation of the case size.
此處,對將光學組件層FX整合於液晶面板P之顯示區域P4的層片進行切斷之後,輸送至另一生產線並貼合至液晶面板P的情況中,該層片及液晶面板P各自的尺寸公差,以及該層片及液晶面板P之相對貼合位置的尺寸公差會疊加,因此難以縮小液晶面板P之邊框部G的寬度(難以使得顯示區域擴大)。 Here, in the case where the layer in which the optical component layer FX is integrated in the display area P4 of the liquid crystal panel P is cut, and then it is conveyed to another production line and bonded to the liquid crystal panel P, the layer and the liquid crystal panel P are each The dimensional tolerance of the lamination sheet and the relative bonding position of the liquid crystal panel P are superimposed, so it is difficult to reduce the width of the frame portion G of the liquid crystal panel P (it is difficult to enlarge the display area).
另一方面,將光學組件層FX貼合至液晶面板P之後,依據顯示區域P4進行切斷的情況中,只需考慮切割線的振動公差,可降低邊框部G之寬度的公差(±0.1mm以下)。此特點亦可使得液晶面板P之邊框部G的寬度變窄(可使得顯示區域擴大)。 On the other hand, when the optical element layer FX is bonded to the liquid crystal panel P and cut in accordance with the display area P4, only the vibration tolerance of the cutting line needs to be considered, and the tolerance of the width of the frame portion G can be reduced (± 0.1 mm). the following). This feature can also make the width of the frame portion G of the liquid crystal panel P narrower (which can expand the display area).
再者,以非利刃的雷射來切斷液晶面板P上的光學組件層FX,切斷時不會有作用力施加至液晶面板P,因此液晶面板P之基板端緣部不易產生裂痕或破裂,提升對於熱循環等的耐久性。同樣地,由於不接觸液晶面板P, 對於電子部件安裝部P5的損傷亦較少。 In addition, the optical component layer FX on the liquid crystal panel P is cut by a non-sharp laser, and no force is applied to the liquid crystal panel P when the cutting is performed. Therefore, the edge of the substrate of the liquid crystal panel P is unlikely to be cracked or broken. To improve durability against thermal cycling and the like. Similarly, since the liquid crystal panel P is not contacted, There is also less damage to the electronic component mounting portion P5.
又,第三貼合裝置18係將具有對應於顯示區域P4之寬度的條狀第三光學組件層F3切斷成特定長度以形成第三光學組件F13。第三貼合裝置18係將該第三光學組件F13與分離層片SS一同輸送,並於進行該切斷的生產線內貼合至第二單面貼合面板P12。因此,與將加工成符合顯示區域P4之偏光板輸送至另一生產線的情況相比,可抑制第三光學組件F13之尺寸偏差或貼合的影響。 The third bonding device 18 cuts the strip-shaped third optical element layer F3 having a width corresponding to the display area P4 to a specific length to form the third optical element F13. The third bonding device 18 conveys the third optical component F13 together with the separation layer sheet SS, and bonds the third optical component F13 to the second single-sided bonding panel P12 in a production line that performs the cutting. Therefore, compared with the case where the polarizing plate processed to conform to the display area P4 is transported to another production line, the influence of dimensional deviation or bonding of the third optical component F13 can be suppressed.
如第6圖所示,以雷射切斷光學組件層FX(第6圖中之第二光學組件層F2)的情況,例如將顯示區域P4之一長邊的延長線上設定為雷射切斷的起點pt1,從該起點pt1先開始進行該一長邊的切斷動作。雷射切斷之終點pt2係設計於雷射環繞顯示區域P4一圈後,到達顯示區域P4之起點側短邊的延長線上之位置。起點pt1及終點pt2係設計使得光學組件層FX之剩餘部分仍會剩餘特定接續部分,而能承受捲取光學組件層FX時的張力。 As shown in FIG. 6, in the case where the optical element layer FX (the second optical element layer F2 in FIG. 6) is cut by a laser, for example, the extension line of one long side of the display area P4 is set as the laser cut. The starting point pt1 at which the long-side cutting operation is performed first. The end point pt2 of the laser cutting is designed after the laser circled around the display area P4 and reached the position on the extension line of the short side of the start side of the display area P4. The starting point pt1 and the ending point pt2 are designed so that the remaining part of the optical component layer FX will still have a specific contiguous portion, and can withstand the tension when the optical component layer FX is rolled up.
如以上說明,上述實施形態中光學顯示設備之生產系統,作為將光學組件(第一光學組件F11、第二光學組件F12及第三光學組件F13)貼合至液晶面板P的光學顯示設備之生產系統,構成其一部分的薄膜貼合系統1中,係具備:貼合裝置(第一貼合裝置12及第二貼合裝置15),係相對沿滾筒輸送機5上輸送之複數個光學顯示部件PX,將在垂直光學顯示部件PX輸送方向之部件寬度方向上具有較該液晶面板P之顯示區域P4之寬度更寬的條狀光學組件層(第一光學組件層F1及第二光學組件層F2),從料捲滾筒(第一料捲滾筒R1及第二料捲滾筒R2)捲出,並將第二光學組件層F2及複數個液晶面板P之第一面(正面與反面的一側之面)依序貼合至該第一次光學組件層F1以形成第二貼合層F22; 第二切斷裝置16,係將對向該顯示區域P4之光學組件層(第一光學組件層F1及第二光學組件層F2)的對向部分,與該對向部分外側的剩餘部分切斷,從該光學組件層(第一光學組件層F1及第二光學組件層F2)切割出具有對應於該顯示區域P4大小的光學組件(第一光學組件F11及第二光學組件F12),並從該第二貼合層F22切割出第二單面貼合面板P12,其包含單一個液晶面板P及與其重疊之光學組件(第一光學組件F11及第二光學組件F12);以及第三貼合裝置18,係相對沿滾筒輸送機5上輸送之複數個第二單面貼合面板P12,將在該部件寬度方向上具有對應於該顯示區域P4之寬度的條狀第三光學組件層F3,從第三料捲滾筒R3與分離層片SS一同捲出,當每次將第三光學組件層F3捲出至對應於該顯示區域P4之長度時,沿寬度方向對該第三光學組件層F3進行切斷,以形成具有對應於該顯示區域P4大小的第三光學組件F13,然後,以該分離層片SS作為載件來輸送複數個第三光學組件F13,並將該第三光學組件F13貼合至該第二單面貼合面板P12之液晶面板P的第二面處(第一面的相反側之面,正面及反面的另一側之面)。 As described above, the production system of the optical display device in the above embodiment is used as an optical display device for bonding the optical components (the first optical component F11, the second optical component F12, and the third optical component F13) to the liquid crystal panel P. The system, which is a part of the film bonding system 1, includes a bonding device (a first bonding device 12 and a second bonding device 15), and a plurality of optical display components conveyed along a roller conveyor 5. PX will have strip-shaped optical component layers (first optical component layer F1 and second optical component layer F2) that are wider than the width of the display area P4 of the liquid crystal panel P in the component width direction of the vertical optical display component PX transport direction ), Roll out from the reel rolls (the first reel roll R1 and the second reel roll R2), and roll the second optical component layer F2 and the first side of the plurality of liquid crystal panels P (front and back sides) Side) sequentially bonded to the first optical component layer F1 to form a second bonding layer F22; The second cutting device 16 cuts the facing portion of the optical component layer (the first optical component layer F1 and the second optical component layer F2) facing the display area P4 and the remaining portion outside the facing portion. , From the optical component layer (the first optical component layer F1 and the second optical component layer F2), an optical component (the first optical component F11 and the second optical component F12) having a size corresponding to the display area P4 is cut, and from The second bonding layer F22 cuts a second single-sided bonding panel P12, which includes a single liquid crystal panel P and optical components (first optical component F11 and second optical component F12) overlapping with it; and a third bonding The device 18 is opposite to the plurality of second single-sided bonding panels P12 conveyed along the roller conveyor 5, and will have a strip-shaped third optical component layer F3 corresponding to the width of the display area P4 in the width direction of the component. It is rolled out from the third roll roll R3 together with the separation layer sheet SS. When the third optical component layer F3 is rolled out to a length corresponding to the display area P4, the third optical component layer F3 is rolled in the width direction. Cut to form a display area corresponding to the display P4 size third optical component F13, and then use the separation layer sheet SS as a carrier to transport a plurality of third optical components F13, and attach the third optical component F13 to the second single-sided bonding panel P12 The second surface of the liquid crystal panel P (the surface opposite to the first surface, the surface opposite to the front and the opposite surface).
根據該結構,將具有對應於顯示區域P4之寬度的條狀第三光學組件層F3切斷成特定長度以形成第三光學組件F13,藉由與第三光學組件層F3一同捲出的分離層片SS作為載件來輸送該第三光學組件F13,並於進行該切斷之生產線內將第三光學組件F1貼合至液晶面板P。因此,與將加工成符合顯示區域P4之偏光板輸送至另一生產線的情況相比,可抑制第三光學組件F13之尺寸偏差或貼合偏差,縮小顯示區域P4周邊之邊框部G,達成顯示區域之擴大及機器之小型化的目的。 According to this structure, the strip-shaped third optical element layer F3 having a width corresponding to the display area P4 is cut to a specific length to form a third optical element F13, and a separation layer rolled out together with the third optical element layer F3 The sheet SS is used as a carrier to convey the third optical component F13, and the third optical component F1 is bonded to the liquid crystal panel P in a production line where the cutting is performed. Therefore, compared with the case where the polarizing plate processed into the display area P4 is transported to another production line, it is possible to suppress the size deviation or the fitting deviation of the third optical component F13, and reduce the frame portion G around the display area P4 to achieve a display. The purpose of expanding the area and miniaturizing the machine.
又,對貼合至液晶面板P後的光學組件層(第一光學組件層F1及 第二光學組件層F2)進行切斷步驟,再與殘留分離層片SS之半切斷後的第三光學組件層F3之貼合步驟加以組合,可達成邊框部G之縮小與輸送間隔時間之縮短的目的。 The optical component layers (the first optical component layers F1 and The second optical component layer F2) is subjected to a cutting step, and then combined with the third optical component layer F3 after the half-cut of the remaining separation layer sheet SS, to achieve a reduction in the frame portion G and a reduction in the transport interval time. purpose.
又,上述光學顯示設備之生產系統,其中該第三貼合裝置18,係具備:滾筒保持部19a,係將該第三光學組件層F3與該分離層片SS一同捲出;切斷裝置19c,係對該第三光學組件層F3進行切斷以作為該第三光學組件F13;第二檢測攝影機23,係在相對該第三光學組件層F3進行切斷之切斷位置,沿該第三光學組件層F3之捲出方向,朝下游側間隔著對應於一個第三光學組件F13之距離的位置處,於該第三光學組件層F3檢測出該切斷所形成的切割線;以及控制裝置20,係從該切斷位置朝該下游側間隔著一個第三光學組件F13之距離的檢測位置處檢測出該切割線時,根據該切割線之位置來調整該切斷位置與該檢測位置之間的距離。 Moreover, in the production system of the above-mentioned optical display device, the third bonding device 18 includes a roller holding portion 19a, which rolls out the third optical component layer F3 together with the separation layer sheet SS, and a cutting device 19c. Is to cut the third optical component layer F3 as the third optical component F13; the second inspection camera 23 is at a cutting position for cutting relative to the third optical component layer F3, along the third The unwinding direction of the optical component layer F3, at a position corresponding to a distance corresponding to a third optical component F13 toward the downstream side, the cutting line formed by the cutting is detected at the third optical component layer F3; and a control device 20, when the cutting line is detected from the cutting position toward the downstream side at a detection position separated by a third optical component F13, the cutting position and the detection position are adjusted according to the position of the cutting line Distance.
根據該結構,藉由位於該第三光學組件層F3之切斷位置下游側相距一個第三光學組件F13距離之位置處的第二檢測攝影機23,檢測出該第三光學組件F13之捲出方向下游側端時,藉由切斷裝置19c對第三光學組件層F3進行切斷,可獲得指定長度之第三光學組件F13。又,即使是第三光學組件層F3的捲出量產生有誤差,可根據第二檢測攝影機23的檢測資料,藉由切斷裝置19c的相對移動以修正(吸收)該誤差。因此,可確保第三光學組件F13的長度之精度,且亦可對應於長度相異之第三光學組件F13的切斷。 According to this structure, the winding-out direction of the third optical element F13 is detected by the second detection camera 23 located at a distance from a third optical element F13 on the downstream side of the cutting position of the third optical element layer F3. At the downstream end, the third optical component layer F3 is cut by the cutting device 19c to obtain a third optical component F13 of a specified length.

Referring to FIG. 14 and FIG. 5 together, the second cutting device 116 simultaneously cuts the second optical component layer F2 and the first optical component layer F1 of the first single-sided bonding panel P11 bonded to the lower side thereof. The ply F1S. The second cutting device 116 has the same configuration as the second cutting device 16 of the first embodiment.

And the second optical component layer F2), the simplification of the cutting step in the first cutting device 113 can be simplified.
藉由第二切斷裝置116的切斷步驟,形成於液晶面板P之上側面重疊貼合有第一光學組件F11及第二光學組件F12的第二單面貼合面板P12(參考第7圖)。又,此時,使第二單面貼合面板P12與切除顯示區域P4之對向部分(各光學組件(第一光學組件F11及第二光學組件F12))後殘餘呈框狀的各光學組件層(第一光學組件層F1及第二光學組件層F2)之剩餘部分能相互分離。第二光學組件層F2之剩餘部分會成為複數相連的梯子狀(參考第14圖),該剩餘部分係與第一光學組件層F1之剩餘部分共同捲取至第二回收部115d。 Through the cutting step of the second cutting device 116, a second single-sided bonding panel P12 is formed on the liquid crystal panel P with the first optical component F11 and the second optical component F12 laminated on the side (see FIG. 7). ). At this time, after the second single-sided bonding panel P12 and the opposing portion of the display area P4 (each optical component (the first optical component F11 and the second optical component F12)) are left, each optical component in a frame shape remains. The remaining portions of the layers (the first optical component layer F1 and the second optical component layer F2) can be separated from each other. The remaining part of the second optical component layer F2 will be in the form of a plurality of connected ladders (refer to FIG. 14), and the remaining part is taken up together with the remaining part of the first optical component layer F1 to the second recovery part 115 d.
參考第13圖,第三校準裝置117將液晶面板P背光側朝向上側面的第二單面貼合面板P12進行正/反面反轉,使得液晶面板P之顯示面側朝向 上側面,進行與該第一校準裝置111及第二校準裝置114相同的校準。即,第三校準裝置117係根據儲存於控制裝置120之光軸方向檢查資料及該攝影機C的攝影資料,決定相對第三貼合裝置118的第二單面貼合面板P12之部件寬度方向及迴轉方向上的位置。在該狀態下,將第二單面貼合面板P12引導至第三貼合裝置118之貼合位置。 Referring to FIG. 13, the third calibration device 117 reverses the front / reverse side of the second single-sided bonding panel P12 with the backlight side of the liquid crystal panel P facing the upper side, so that the display surface side of the liquid crystal panel P faces On the upper side, the same calibration as that of the first calibration device 111 and the second calibration device 114 is performed. That is, the third calibration device 117 determines the component width direction and the width of the second single-sided bonding panel P12 of the third bonding device 118 based on the inspection data of the optical axis direction stored in the control device 120 and the photographic data of the camera C. Position in the direction of rotation. In this state, the second single-sided bonding panel P12 is guided to the bonding position of the third bonding device 118.
如第13圖及第16圖所示,第三貼合裝置118,係具備:輸送裝置119,係從一同捲繞有第三光學組件層F3和與其重疊之分離層片SS的第三料捲滾筒R3將第三光學組件層F3及分離層片SS捲出並進行輸送,且從第三光學組件層F3切割出第三光學組件F13以供給至貼合位置;以及夾壓滾筒121,係將輸送裝置119從第三光學組件層F3切割出之第三光學組件F13的下側面貼合至滾筒輸送機105所輸送之第二單面貼合面板P12的上側面(液晶面板P之顯示面側)。 As shown in FIGS. 13 and 16, the third bonding device 118 is provided with a conveying device 119 from a third roll in which a third optical element layer F3 and a separation layer sheet SS overlapped therewith are wound together. The roller R3 rolls out and conveys the third optical component layer F3 and the separation layer sheet SS, and cuts out the third optical component F13 from the third optical component layer F3 to be supplied to the bonding position; The lower side of the third optical component F13 cut from the third optical component layer F3 by the conveying device 119 is bonded to the upper side of the second single-sided bonding panel P12 conveyed by the roller conveyor 105 (the display surface side of the liquid crystal panel P). ).
輸送裝置119與第一實施形態之輸送裝置19相同般,以分離層片SS作為載件連續地輸送複數個第三光學組件F13。輸送裝置119,係具備:滾筒保持部119a(捲出部),係夾持第三料捲滾筒R3並從該第三料捲滾筒R3沿第三光學組件層體F3S之長邊方向將第三光學組件層體F3S捲出;單數或複數個(圖中僅顯示一個)導引滾筒119b,沿特定之層片輸送路線將從第三料捲滾筒R3捲出之第三光學組件層體F3S引導至第三貼合裝置118的貼合位置為止,沿第三光學組件層體F3S之分離層片SS側捲繞;切斷裝置119c(切斷部),會對層片輸送路線上之第三光學組件層體F3S進行殘留下分離層片SS的半切斷;刀刃119d,呈銳角般沿著半切斷後之第三光學組件層體F3S的分離層片SS側進行捲繞,使第三光學組件F13從分離層片SS分離,將第三光學組件F13供給至貼合 位置;以及分離層片回收部119e,捲取通過刀刃119d後獨自存在之分離層片SS。 The transporting device 119 is the same as the transporting device 19 of the first embodiment, and continuously transports the plurality of third optical units F13 with the separation layer sheet SS as a carrier. The conveying device 119 is provided with a roller holding portion 119a (rolling-out portion) for holding the third roll roller R3 and moving the third roll roller R3 from the third roll roller R3 along the longitudinal direction of the third optical component layer body F3S. The optical component layer body F3S is rolled out; the singular or plural (only one shown in the figure) guide roller 119b guides the third optical component layer body F3S rolled out from the third material roll roller R3 along a specific layer conveying route. Up to the bonding position of the third bonding device 118, it is wound along the separation layer SS side of the third optical component layer body F3S; the cutting device 119c (cutting section), The optical component layer body F3S performs half-cutting of the remaining separation layer sheet SS; the blade 119d, at an acute angle, is wound along the separation layer sheet SS side of the third optical module layer body F3S after half-cut, so that the third optical module F13 Separate from the separation layer sheet SS, and supply the third optical module F13 to the bonding Position; and a separation layer recovery part 119e, which winds up the separation layer SS that exists alone after passing through the blade 119d.
位於輸送裝置119之起點的滾筒保持部119a與位於輸送裝置119之終點的分離層片回收部119e係例如為相互同步驅動。藉此,滾筒保持部119a係朝第三光學組件層體F3S之輸送方向捲出第三光學組件層體F3S,且分離層片回收部119e則捲取通過刀刃119d後獨立存在之分離層片SS。 The roller holding portion 119 a located at the start point of the conveying device 119 and the separation layer recovery portion 119 e at the end point of the conveying device 119 are driven in synchronization with each other, for example. Thereby, the roller holding portion 119a rolls out the third optical component layer body F3S in the conveying direction of the third optical component layer body F3S, and the separation layer sheet recovery portion 119e winds up the separation layer sheet SS which exists independently after passing through the blade 119d .
在第三光學組件層體F3S捲出特定長度時,切斷裝置119c係在垂直第三光學組件層體F3S之長邊方向(捲出方向)的寬度方向上,殘餘分離層片SS地沿整體寬度對第三光學組件層體F3S進行切斷(即僅切斷第三光學組件層F3)。切斷裝置119c係透過第三光學組件層體F3S輸送中的張力,在不使得分離層片SS斷裂的情況下調整切斷刀片的前後位置。 When the third optical component layer body F3S is rolled out a certain length, the cutting device 119c is in a width direction perpendicular to the long side direction (rolling direction) of the third optical component layer body F3S, and the residual separation layer SS is along the whole The width cuts the third optical component layer body F3S (that is, only the third optical component layer F3 is cut). The cutting device 119c adjusts the forward and backward positions of the cutting blade without breaking the separation layer sheet SS through the tension in the conveyance of the third optical component layer F3S.
於該切斷步驟後之第三光學組件層體F3S處,在第三光學組件層體F3S之寬度方向的整體寬度上形成有切割線。 At the third optical component layer body F3S after the cutting step, a cutting line is formed on the entire width of the third optical component layer body F3S in the width direction.
此處,於刀刃119d之前端部附近,在第三貼合裝置118之貼合位置附近的面板輸送上游側之部位處,設置有檢測該部位中第三光學組件F13的捲出方向下游側之切斷端的第一檢測攝影機122。第一檢測攝影機122之檢測資料係傳送至控制裝置120。控制裝置120於例如第一檢測攝影機122檢測出第三光學組件F13之下游側端的時點時,係暫時停止輸送裝置119。其後,於第一檢測攝影機122檢測出第二單面貼合面板P12之下游側端的時點時,控制裝置120係驅動輸送裝置119,第二單面貼合面板P12與第三光學組件F13可同步地引導至第三貼合裝置118的貼合位置。 Here, near the front end of the blade 119d, at a portion on the upstream side of the panel conveyance near the bonding position of the third bonding device 118, a detection is performed on the downstream side of the third optical component F13 in this portion. The first detection camera 122 at the cut end. The detection data of the first detection camera 122 is transmitted to the control device 120. The control device 120 temporarily stops the conveying device 119 when, for example, the first detection camera 122 detects a downstream end of the third optical unit F13. Thereafter, when the first detection camera 122 detects the downstream end of the second single-sided bonding panel P12, the control device 120 drives the conveying device 119, and the second single-sided bonding panel P12 and the third optical component F13 may It is synchronously guided to the bonding position of the third bonding device 118.
另一方面,於第一檢測攝影機122之捲出方向上游側,在切斷裝置119c之捲出方向下游側相距一個第三光學組件F13之距離的部位處,設置有 同樣檢測第三光學組件F13的捲出方向下游側之切斷端的第二檢測攝影機123。第二檢測攝影機123的檢測資料亦傳送至控制裝置120。控制裝置120係以例如切斷裝置119c進行第三光學組件層F3切斷步驟後將其捲出,在第二檢測攝影機123檢測出其切斷端(第三光學組件層F3之最上游側的切割線)的時點時,暫時停止輸送裝置119。此時,以切斷裝置119c進行第三光學組件層F3的切斷步驟。即,沿第二檢測攝影機123之檢測位置(相當位於第三光學組件層F3中第二檢測攝影機123之光軸延長線上)與切斷裝置119c之切斷位置(相當於第三光學組件層F3中切斷裝置119c的切斷刀片前後位置)間的層片輸送路線之距離係相當於第三光學組件F13的長度。 On the other hand, on the upstream side in the unwinding direction of the first detection camera 122, at a position away from the third optical unit F13 on the downstream side in the unwinding direction of the cutting device 119c, Similarly, the second detection camera 123 that detects the cut-off end downstream of the third optical unit F13 in the unwinding direction. The detection data of the second detection camera 123 is also transmitted to the control device 120. The control device 120 performs the cutting step of the third optical component layer F3 by, for example, the cutting device 119c, and rolls it out, and the second detection camera 123 detects the cut end (the most upstream side of the third optical component layer F3). Cutting line), the conveyor 119 is temporarily stopped. At this time, the cutting step of the third optical element layer F3 is performed by the cutting device 119c. That is, along the detection position of the second detection camera 123 (corresponding to the optical axis extension line of the second detection camera 123 in the third optical component layer F3) and the cutting position of the cutting device 119c (equivalent to the third optical component layer F3) The distance between the layer conveying paths between the cutting blades in the middle cutting device 119c) corresponds to the length of the third optical unit F13.
又,切斷裝置119c可沿第三光學組件層體F3S之層片輸送路線移動。透過該移動步驟,將改變第二檢測攝影機123之檢測位置與切斷裝置119c之切斷位置間的層片輸送路線之距離。切斷裝置119c的移動係透過控制裝置120所控制,在以例如切斷裝置119c進行第三光學組件層F3的切斷之後,捲出一個第三光學組件F13之距離時,當切斷端位置與指定位置有偏差的情況中,該偏差係藉由切斷裝置119c的移動以進行修正。 In addition, the cutting device 119c can move along the sheet conveyance path of the third optical element layer body F3S. Through this moving step, the distance of the laminar conveyance path between the detection position of the second detection camera 123 and the cutting position of the cutting device 119c will be changed. The movement of the cutting device 119c is controlled by the control device 120. After the third optical component layer F3 is cut by, for example, the cutting device 119c, and the third optical component F13 is rolled out, the cutting end position When there is a deviation from the designated position, the deviation is corrected by the movement of the cutting device 119c.
不過,亦可藉由切斷裝置119c的移動來對應長度相異之第三光學組件F13的切斷。又,亦可使得切斷裝置119c及第二檢測攝影機123至少一者在層片輸送方向的一方向上移動,藉以進行該修正或第三光學組件F13的長度改變。又,雖然切斷裝置119c與第二檢測攝影機123相互接近,但為了防止切斷裝置119c移動等所伴隨的第二檢測攝影機123振動,較佳地可由其它框架所支撐。 However, the movement of the cutting device 119c may be used to cut the third optical module F13 having a different length. In addition, at least one of the cutting device 119c and the second detection camera 123 may be moved upward in one of the slice conveying directions to perform the correction or change the length of the third optical unit F13. In addition, although the cutting device 119c and the second detection camera 123 are close to each other, in order to prevent the second detection camera 123 accompanying the movement of the cutting device 119c and the like from being vibrated, it is preferably supported by another frame.
刀刃119d係配置於滾筒輸送機105上方,第三光學組件層體 F3S的寬度方向上至少延伸至其整個寬度地被形成。刀刃119d係於半切斷後之第三光學組件層體F3S的分離層片SS側呈滑動接觸地,使分離層片SS捲繞過此銳角。 The blade 119d is arranged above the roller conveyor 105, and the third optical component layer body The F3S is formed so as to extend over at least the entire width of the F3S. The blade 119d is on the side of the separation layer sheet SS of the third optical component layer body F3S after half-cutting, and the separation layer sheet SS is wound around this acute angle.
第三光學組件層體F3S在刀刃119d呈銳角處折返時,第三光學組件F13會從分離層片SS分離。刀刃119d係配置於接近夾壓滾筒121的面板輸送上游側。藉由刀刃119d從分離層片SS分離的第三光學組件F13係重疊至滾筒輸送機105所輸送之液晶面板P的上側面,且被引導至夾壓滾筒121的一對貼合滾筒之間。 When the third optical component layer body F3S is folded back at an acute angle of the blade 119d, the third optical component F13 is separated from the separation layer sheet SS. The blade 119 d is disposed on the upstream side of the panel conveyance near the nip roller 121. The third optical component F13 separated from the separation sheet SS by the blade 119d is superimposed on the upper side of the liquid crystal panel P conveyed by the roller conveyor 105, and is guided between a pair of laminating rollers sandwiching the roller 121.
夾壓滾筒121具有於軸線方向相互平行配置的一對貼合滾筒。一對貼合滾筒之間形成有指定間隙,該間隙內即為第三貼合裝置118的貼合位置。將第二單面貼合面板P12及第三光學組件F13重合導入該間隙內。該等第二單面貼合面板P12及第三光學組件F13係於該貼合滾筒之間受夾壓,並送往面板輸送下游側。藉此,便可形成將第三光學組件F13貼合至第二單面貼合面板P12的雙面貼合面板P13(參考第7圖)。 The nip roller 121 includes a pair of bonding rollers arranged in parallel with each other in the axial direction. A specified gap is formed between the pair of bonding drums, and the gap is the bonding position of the third bonding device 118. The second single-sided bonding panel P12 and the third optical component F13 are overlapped and introduced into the gap. The second single-sided bonding panel P12 and the third optical component F13 are sandwiched between the bonding rollers and sent to the downstream side of the panel transportation. Thereby, a double-sided bonding panel P13 (refer to FIG. 7) in which the third optical component F13 is bonded to the second single-sided bonding panel P12 can be formed.
與第一實施形態之輸送裝置19相同,雙面貼合面板P13通過圖中未顯示之缺陷檢查裝置,以檢查是否有缺陷(貼合不良等)後,輸送至下游步驟進行其它處理。 Similar to the conveying device 19 of the first embodiment, the double-sided bonding panel P13 is inspected by a defect inspection device (not shown in the figure) for defects (such as poor bonding), and then conveyed to a downstream step for other processing.
又,與上述第一實施形態之控制裝置20相同,本實施形態的情況中,該檢查裝置所獲得之各光學組件層(第一光學組件層F1、第二光學組件層F2及第三光學組件層F3)之光軸方向的檢查資料係與各光學組件層(第一光學組件層F1、第二光學組件層F2及第三光學組件層F3)之長邊方向位置與寬度方向位置資料連結般地儲存於控制裝置120之記憶體。又,與上述第一實施形態相 同,經檢查之後,各自捲取各光學組件層(第一光學組件層F1、第二光學組件層F2及第三光學組件層F3),以形成各料捲滾筒(第一料捲滾筒R1、第二料捲滾筒R2及第三料捲滾筒R3)。 The control device 20 is the same as the control device 20 in the first embodiment. In the case of this embodiment, each optical component layer (the first optical component layer F1, the second optical component layer F2, and the third optical component) obtained by the inspection device. The inspection data in the optical axis direction of the layer F3) is connected to the position data in the longitudinal direction and the position in the width direction of each optical component layer (the first optical component layer F1, the second optical component layer F2, and the third optical component layer F3). Ground is stored in the memory of the control device 120. It is similar to the first embodiment described above. Similarly, after inspection, each optical component layer (the first optical component layer F1, the second optical component layer F2, and the third optical component layer F3) is rolled up to form each roll roll (the first roll roll R1, The second roll drum R2 and the third roll drum R3).
本實施形態中,與第一實施形態之控制裝置20相同,根據預先儲存於控制裝置120之光學組件層FX各部位中的光軸面內分佈檢查資料,進行與其貼合之光學顯示部件PX的校準後,將光學顯示部件PX貼合至光學組件層FX。藉此,獲得與第一實施形態相同的效果。 In this embodiment, similar to the control device 20 of the first embodiment, the optical display component PX bonded to the optical display component PX is carried out based on the inspection data of the optical axis plane distribution stored in each part of the optical component layer FX of the control device 120 in advance. After the calibration, the optical display component PX is bonded to the optical component layer FX. Thereby, the same effect as that of the first embodiment is obtained.
又,第15圖係於相對較寬的光學組件層FX之寬度方向上並列貼合有三個光學顯示部件PX的範例,本發明並不限於此,亦可於光學組件層FX之寬度方向上並列貼合有二個以下或四個以上的光學顯示部件PX,亦可將相對較窄的光學組件層FX沿寬度方向排列複數個,並各自貼合光學顯示部件PX。 15 is an example in which three optical display components PX are laminated side by side in the width direction of a relatively wide optical component layer FX. The present invention is not limited to this, and can also be juxtaposed in the width direction of the optical component layer FX. Two or less or four or more optical display components PX are bonded, and a plurality of relatively narrow optical component layers FX may be arranged in the width direction, and each of the optical display components PX may be bonded.
參考第5圖,第二切斷裝置116以攝影機116a等檢測工具檢測顯示區域P4之外周緣,並沿顯示區域P4之外周緣等切斷第一光學組件層F1及第二光學組件層F2。顯示區域P4之外側處係設置有將第一基板P1及第二基板P2接合之密封劑等設置用特定寬度的邊框部G,於該邊框部G之寬度內以第二切斷裝置116進行雷射切斷。 Referring to FIG. 5, the second cutting device 116 detects the outer periphery of the display area P4 with a detection tool such as a camera 116 a, and cuts the first optical component layer F1 and the second optical component layer F2 along the outer periphery of the display area P4 and the like. Outside the display area P4, a frame portion G having a specific width for installation, such as a sealant that joins the first substrate P1 and the second substrate P2, is provided. Within the width of the frame portion G, a second cutting device 116 is used for lightning. Shoot off.
藉有使用該切斷裝置,可獲得與第一實施形態相同的效果(參考第9圖及第10圖)。 By using this cutting device, the same effect as that of the first embodiment can be obtained (see FIGS. 9 and 10).
又,第三貼合裝置118係將具有對應於顯示區域P4之寬度的條狀第三光學組件層F3切斷成特定長度以形成第三光學組件F13。第三貼合裝置118係將該第三光學組件F13與分離層片SS一同輸送,並於進行該切斷的生產線內貼合至第二單面貼合面板P12。因此,與將加工成符合顯示區域P4之偏光 板輸送至另一生產線的情況相比,可抑制第三光學組件F13之尺寸偏差或貼合的影響。 The third bonding device 118 cuts the strip-shaped third optical element layer F3 having a width corresponding to the display area P4 to a specific length to form the third optical element F13. The third bonding device 118 conveys the third optical component F13 together with the separation layer sheet SS, and bonds the third optical component F13 to the second single-sided bonding panel P12 in a production line that performs the cutting. Therefore, the polarized light will be processed to fit the display area P4. Compared with the case where the board is transported to another production line, the influence of dimensional deviation or bonding of the third optical component F13 can be suppressed.
如第6圖所示,以雷射切斷光學組件層FX(第6圖中之第二光學組件層F2)的情況,例如將顯示區域P4之一長邊的延長線上設定為雷射切斷的起點pt1,從該起點pt1先開始進行該一長邊的切斷動作。雷射切斷之終點pt2係設計於雷射環繞顯示區域P4一圈後,到達顯示區域P4之起點側短邊的延長線上之位置。起點pt1及終點pt2係設計使得光學組件層FX之剩餘部分仍會剩餘特定接續部分,而能承受捲取光學組件層FX時的張力。 As shown in FIG. 6, in the case where the optical element layer FX (the second optical element layer F2 in FIG. 6) is cut by a laser, for example, the extension line of one long side of the display area P4 is set as the laser cut. The starting point pt1 at which the long-side cutting operation is performed first.
